DETROIT (Reuters) - Volkswagen AG is recalling about 334,000 Volkswagen and Audi brand vehicles in the United States and Canada in three separate recalls, each due to fuel leaks but with different causes, U.S. safety regulators and VW said on Friday.

No one has been injured as a result of these issues, Volkswagen spokeswoman Jeannine Ginivan said on Friday. While the fuel leaks could increase the risk of fire, there have been no fires reported, she said.

About 83 percent of the recalled vehicles are registered in the United States.

Volkswagen did not immediately say whether the recalls will affect vehicles outside of North America.

The company did not say how much it expects the recalls to cost. VW said it will notify affected vehicle owners instructing them when parts will be available for them to go to VW and Audi dealerships for repairs free of charge. In the meantime, VW said it will send out interim notifications to affected consumers in November.
